JESSE E. FISHER, OF LEMMON, SOUTH DAKOTA.

BELT-GUIDE.

T 0 all whom it may concern:

Be it known that I, Jnssn E. FISHER, a citizen of the United States,residing at Lemmon, in the county of Perkins, State of South Dakota,have invented certain new 'and useful Improvements in Belt-Guides;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in belt shifters, and moreparticularly to the type employed with harvesting machinery.

It is well known that considerable difli culty is experienced inmaintaining the belt connection between an engine and harvesting machinein position. This is due to the fact that the vibration of both theengine and harvester tends to change the alinement between the two; andthen again the belt used for connecting the pulley and fly-wheel isoften of rubber and when wet slips and becomes disengaged from thepulley and fly wheel.

The present invention aims to remedy these defects by providing a devicewhich will positively prevent the belt from leaving the fly wheel andpulley during the operation of the engine and machine.

Another object is the provision of a means for disengaging the belt fromthe fly wheel and pulley in an expeditious manner whenever desired andwithout any danger to the operator.

With these and other objects in view as i will more fully hereinafterappear, the pres ent invention consists in certain novel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings and more particularly pointedout in the appended claims. It being understood that various changes inthe form proportion, size and minor details of the device may be madewithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the accompanying drawings forming part of the specification z-Figure1 is a side elevation of a boiler and engine equipped with my device andalso showing a portion of a harvesting machine. Fig. 2 is a front endelevation of the device showing the position of the parts before thebelt has been detached. Fig. 3 is a similar view showing Specificationof Letters Patent.

the position of the parts after the belt has been detached. Fig. 4- is aplan view taken on the line t4, of Fig. 2 and showing the position ofthe belt detacher. Fig. 5 is a longitudinal section on the line 55 ofFig. 2 and showing the actuating mechanism for the belt detacher.elevation taken on the line 66 of Fig. 1. Fig. 7 is a detailedlongitudinal section of one of the rollers.

Similar numerals of reference are employed to designate correspondingparts throughout.

As shown in the drawings the numeral 5 designates the boiler, 6 the flywheel and 7 the pulley of the machine to be driven.

8 is the belt connection between the pulley and fly wheel.

The boiler and engine in the present in stance are shown to be of aportable type such as are usually transported from one farm to anotherduring the harvesting. Encircling that portion of the boiler between itsforward end and fly wheel 6 is a strap 9. This member is preferablyformed of two or more sections which are bolted together as shown.Secured to that section of the strap disposed on the top and that sideof the boiler on which the fly wheel 6 is disposed is one end of abracket 10. This member is preferably formed of a single piece of metalcorresponding in width and thickness to the strap sections and extendslaterally of the boiler, to a point within the plane of the fly wheel 6where it terminates in a downwardly turned extension which liestangentially of the side of the boiler and strap 9.

Fixedly secured to the down-turned portion at the outer end of thebracket and strap 9 is what will subsequently be termed a guide 11. Thismember is preferably formed of a single piece of sheet metal, oblong incontour and having spaced strips on its outer face so as to constituteguides. This member is disposed tangentially to the side of the boilerand is of a length corresponding to the diameter of the fly-wheel 6, orapproximately so. Projecting forwardly from the upper and lower endportions of the guide 11 are a pair of brackets 12 and 13 which extendparallel with the length of the boiler and the upper sides of which areprovided with lateral lugs 14: and 15 which extend outwardly and atrightangles to the vertical plane of the boiler. These lugs are Fig. 6is a sectional end i provided with alining openings which receive theopposite end portions of a standard 16, which is adjustably securedtherein by means of set screws 17 entering the transverse openingsformed in the lugs. Owing to the position of the parts just describedthey will lie a slight distance within the plane of the fly-wheel so asnot to bear against the belt 8.

The standard 16 is adapted to support the rollers for the belt, thesemembers are adapted to bear on the inner and outer faces of the belt andin the present instance are shown to be formed of wood mounted onbrackets, the upper bracket is designated by the numeral 18 and ispreferably formed of a single piece of fiat metal, oblong in contour andprovided on one side with a rearwardly extending lug 19 which isprovided with an opening to receive the upper end portion of thestandard. A set screw 20 is threaded into the lug and binds against thestandard, whereby the bracket is adjustably secured thereon. The bracketextends at right-angles to the standard and at its opposite ends isprovided with vertically extending perforated cars 21 which receive theopposite end portions of a shaft 22 journaled therein. The opposite endsof the shaft 22 project beyond the ears 21 and these end portions aresquared. Keepers 23 and 2% are fixedly secured to the projecting ends ofthe shaft 22 and are each shown to consist of an oblong strip which issecured to the shaft by means of a set screw, whereby they may beadjusted longitudinally of the shaft. The distance between these keeperscorresponds to the width of the belt to be used so that the latter willbear on their opposed inner faces and be prevented from displacement.JOurnaled on the shaft 22 and between the keepers 23 and 24 is a tubularroller 25 upon which the upper side of the belt 8 is adapted to bear.

The lower bracket is of different structure to the upper bracket and inthe present iristance is shown to consist of an oblong metallic plate ofslightly greater width than the upper bracket. This member is providedon its forward side and at itsinner end with a forwardly extending lug27 which is pro vided w'th an opening for the reception of the standard15. A set screw is threaded into the lug and binds against the standardand serves as a means for fastening the bracket thereto. The plate isprovided adjacent its rear side with a longitudinal slot 28 and isfurther provided at either end with tip-standing lugs or ears 29 similarto the lugs or ears 21 of the upper bracket. These lugs or ears aredisposed in advance of the slot 28 and adjacent the forward side of theplate and are adapted to receive the opposite ends of shaft 30 which isjournaled therein. The free ends of the shaft 30 extend in advance ofthe lugs 29 and terminate in squared portions on which are fitted a pairof keepers 31 and 32 similar to the keepers 23 and 24 but extending inan opposite direction to the last-named keepers. naled on the shaft 30and between the ears or lugs 29 is a tubular roller 33, on which runsthe belt 8 between the keepers 31 and 32 and which prevents the lowerside of the belt from displacement. The rollers 25 and 33 lie in avertical plane, or substantially so, and are arranged in the plane ofthe flywheel 6 and pulley 7. The lower roller 33 is so arranged on theplate 26 as to be in advance of the longitudinal slot 28.

Disposed within the guide 11 are a pair of slides 34: and 35 each ofwhich correspond to one-fourth the length of the guide 11, orapproximately so. The inner ends of these slides terminate in outwardlyprojecting lugs 36 which are arranged so as not to interfere with themovement of the slides; the lugs terminate in knuckles which interlockwith the knuckles on the ends of a pair of links 37 and 38'. The latterare preferably formed of pieces of sheet metal and at their outer endsare provided with interlocking knuckles which receive pintle by means ofwhich they are held together, the combined lengths of the slides andlinks when the latter are in a vertical position correspondapproximately to the length of the guide. Thus it can be seen that theslides may be brought together, whereby the inner faces of the linkswill hear one upon the other and the links be disposed at a right-angleto the guide and when the slides are supported the links will assume avertical position and be parallel with the guide. The links are soarranged that their forward sides lie adjacent the rear side of theplate 26 of the lower bracket, and swiw eled in an opening at the outersides of the interlocking ends of the links is the shank end of asubstantially Y shaped carrier 39. The shank portion of this carrier isbent at right-angles and extends forwardly so that the limbs of the Ywill straddle the lower bracket plate 26 and have their inner endsdisposed over the longitudinal slot 28 of said plate. The inner endportions of the limbs of the carrier are provided with alining openingsfor the reception of a vertically disposed thrower 40 which extendsthieugh the longitudinal slot 28 of the lower bracket plate and bears onthe edge of the belt. Thus it will be seen when the slides are broughttogether and the links forced outwardly the carrier will take thethrower to the outer end of the longitudinal slot and when the slidesare operated and the links assume a vertical position the carrier andthrower will move to the opposite end of the slot 28. Thus it will beseen when the thrower is in the lastnanied position and the belt isrunning on the fiy-wh'e'el and pulley that by bringing the J our- 1links and slides together as just described, the thrower engaging theend of the belt will forcethe latter bodily outward, whereby it will bedisengaged from the fly-wheel and pulley, that is when the keepers areout of engagement with the sides of the belt, as will be presentlydescribed.

In order that the slide may be brought together mechanically and thethrower perform its function the following construction is employed: Byreferring now to the drawings it will be seen that a screw shaft 41 isthreaded into the projecting lugs 36 of the slides, the opposite endportions of this screw shaft are provided with right and left threads,while the intermediate portion has keyed thereto a beveled pinion 42.Thus it will be seen when the pinion is turned and the shaft rotated theslides and links will operate, as before described. Secured to the outerface of the boiler and adjacent the rear end thereof is a bracket 13 andjournaled in this bracket is one end of a rod 44, the opposite end ofwhich extends to the guide 11 and is provided at this end with a'beveledpinion 45, the teeth of which mesh with the pinion 42] In order toprevent displacement of the screw shaft 41 its intermediate portiondirectly beneath the pinion 4:2 is provided with a collar and encirclingthat portion of the shaft between the collar and lower face of a pinionis one end of a bracket 46, the opposite end of which extends rearwardlyand encircles that portion of the rod 44 to the rear of the pinion 45.The bracket 46 may be made in any shape in order to establish thisconnection and thus it will be seen that owing to its engagement withthe screw and rod that displacement of the former will be prevented. Theopposite end of the rod 44: to the rear of the bracket 43 termi nates ina hand wheel 4C7 which is within easy reach of the engine operator. Thusit can be seen when it is desired to throw the belt, it being understoodthat the thrower is at the inner end of the slot 28, all that will benecessary to do is to turn the hand wheel 47 in one direction, wherebythe thrower through the medium of the carrier, links and the gearconnection will move outwardly and disengage the belt from the pulleyand fiy-wheel.

In order that the keepers may be disengaged from the sides of the beltto permit the thrower to perform its function the following constructionis employed: By referring now to the drawings it will be seen thatsecured to the inner face of the upper bracket 13 and extending inadvance of the upper end of the guide is a bell crank lever 48, one armof which extends forwardly and the other vertically upward, connectionbetween the forwardly extending arm of the bell crank and the innerkeeper 32 of the lower bracket is established by means of a connectingrod 49, the opposite ends of which are pivoted to the free end portionsof the keeper and forwardly extending arm of the bell crank. A secondrod 50 connects the inner keeper 24 of the upper bracket with the samearm of the bell crank lever and extending from the opposite arm of thebell crank lever is an operating rod 51, the rear end of which extendsto a point within easy reach of the engine operator at the rear end ofthe boiler. This end of the rod is on its lower face provided withsuitable notches 1 or teeth 52 which engage a keeper 53, when the rod ismoved, the upper keepers will be rocked out of engagement with the beltso also will the lower keepers be rocked from engagement with the sidesof the belt. This will be the position of the parts when it is necessaryto throw the belt from the fiy wheel and pulley.

Thus it will be seen that I have provided a device which is exceedinglysimple in structure and comparatively inexpensive to manufactureembodying few parts and these so arranged that the danger of derangementwill be reduced to a minimum. It will be further seen that the parts areso arranged that they may be applied to most forms of boilers of thisclass, now in use.
